Book excerpt: Dan Gookin loves a challenge. He must, otherwise he wouldn't have taken on so daunting a topic as the C programming language. And as you can see from C For Dummies, Volume One, Gookin was definitely up to the task: Right off the bat, this plain-English guide to programming in one of the most widely accepted computer languages can have you coding in C just like a pro. Using your C compiler of choice -- whether it's Borland C++, Turbo C, Microsoft Visual C++, or some other -- you'll get the hang of the basic building blocks of C programs, from printf to scanf.
